General Maintenance Suggestions
Model (CBF-205) concrete block exhaust fan
requires very little maintenance. However,
since small problems left unchecked could
over time lead to loss of performance or early
motor failure, we do recommend that the unit
be inspected periodically (once or twice a
year).
The fan motor and wheel(s) should be
checked for dust and dirt accumulations. Dirt
buildup can lead to loss of performance and
motor overheating. Cleaning can be
accomplished by brushing of any dust that
may have accumulated.
